Subject [jira] Commented: (VALIDATOR-232) Add script attribute to control script generation
Date Wed, 11 Jul 2007 00:03:05 GMT


Paul Benedict commented on VALIDATOR-232:

I don't use any javascript validation on my apps because, specifically, I do not want to expose
any mask elements. In a perfect world, I could switch off validation scripting for these fields
-- not just password fields -- on an as-needed basis. But because I don't have this freedom,
I only do server side validation. And if I had this option, I may find in the future how useful
this is for other things... 

You raise a good point about switching off validations per type or substituting corrected
scripts. However, you'd be surprise how many good java developers do not know javascript :-)
In some instances, a person may simply just choose to turn it off rather than replace it.

I've been viewing this issue to something like CSS stylesheets. With the CSS "media" attribute,
and I get to say which media the styling belongs (screen, printer, audio, etc.). Likewise,
I believe it is good to give developers the freedom to direct what media the validation belongs.
For Commons Validator, there's two media components: scripting and Java. If I don't care for
how a script works, I'd be more willing to disable it and rely on the server-side version
than replace it.

While I haven't done this yet, I'd be very interested in replacing some client-side validation
with perhaps DOJO/Ajax validation. I may want to (1) have only one form field that uses Web
2.0 features, (2) keep the standard JS validation on other fields but (3) still rely on the
server-side validation for all fields as "standard practice". It opens up some interesting
possibilities here.
